I Need Some Ideas Please.

I need some ideas for a birthday/Easter cake. My family is getting together this weekend to celebrate Easter and my sister's birthday. She is a landscape architecht and I would like to surprise her with a special cake. I was thinking of some sort of a chocolate jelly roll cake with a hazenut filling and fudge icing to make it look like a yule log but to have bunnies and birds peeking out of the holes. But this would be more for the 8 children that will be there. Does anyone have any other ideas??? She does a lot of park themes, should I go that way?? Or the jelly log for the kids and a tiramisu dessert for her, that's her favorite. What do you think??

You could do a sheet cake with a green landscape/park theme and then put the yule log with the bunnies and everything coming out of it, on top of the landscape cake. You would just want to make it proportional.
